On Windows, when creating a snapshot (renaming a checkpoint), occasionally prim_file:rename failed with `eacces`. It's not clear why this happens, it appears that Windows may not release the file handle immediately after closing the file so a close->rename in a quick succession may sometimes return an error. With this commit, we just retry after 20ms and so far, in our testing, the error has never occurred on the second attempt (with a 10ms delay, it still failed every now and then) We could have separate macros for eagain and eaccess, but I went with a share one. One retry seems reasonable in both cases.
